Mean values and 5th and 95th percentiles (in parentheses) are reported.*Total sample comprises individuals of African ancestry (n = 7), East Asian ancestry (n = 27), European ancestry (n = 32), Other ancestry (n = 9), and South Asian ancestry (n = 32). #25(OH)D measurements were not available for one individual of South Asian ancestry, hence n = 106 for this variable.
